Weiner's research and teaching are informed by the several years he spent as a high-level aide and consultant in national politics, including serving as Communications and Policy Director to U.S. Senator Bob Kerrey, D-Nebraska, and as founder of the Washington, D.C.-based speechwriting firm Content Communications, LLC.

"Like James Madison, Daniel Patrick Moynihan was the most interesting public intellectual of his day and he refined his systematic political thinking during decades in the practice of politics. Greg Weiner's masterful exegesis demonstrates that Moynihan's robust liberalism was informed, but never deformed, by his Burkean sense of the purposes and limits of politics.”
-George F. Will

"Few American senators of the past century would be worthy of an extended study of their political philosophy, but Daniel Patrick Moynihan certainly was. American Burke is a fascinating and brilliant account of what was an unusual political philosophy for a successful American politician—a liberal, yes, but one aware of the complexity of society and social institutions, the difficulty of molding or remolding them, the worth of traditional institutions and arrangements, and yes, something of an American Burke, And all this was expressed in the most engaging and sparkling style of any political figure of recent generations. Whatever else is written of Moynihan, and there will be much, this will stand as a classic."
-Nathan Glazer, coauthor with Moynihan of Beyond the Melting Pot
